Description

U+01DE, the Latin Capital Letter A with Diaeresis and Macron, is a unique Unicode character that serves a specific role in digital text. It is primarily used in typography to represent the 'A' vowel sound found in certain languages, such as French, German, and Dutch. In these languages, the character is utilized to indicate the pronunciation of the letter "A" with both a diaeresis (the two dots) and a macron (the horizontal line above the letter), signifying a distinct sound from the regular "A." This character is an essential tool for accurate and clear communication in these languages, where the nuances of vowel sounds are crucial to proper pronunciation and comprehension. Its precise use showcases the richness and diversity of linguistic expression within the Unicode system, ensuring that digital text remains faithful to its original intent across various cultures and languages.

How to type the Ǟ symbol on Windows

Hold Alt and type 0478 on the numpad. Or use Character Map.

  1. Step 1: Determine the UTF-8 encoding bit layout

    The character Ǟ has the Unicode code point U+01DE. In UTF-8, it is encoded using 2 bytes because its codepoint is in the range of 0x0080 to 0x07ff.

    Therefore we know that the UTF-8 encoding will be done over 11 bits within the final 16 bits and that it will have the format: 110xxxxx 10xxxxxx
    Where the x are the payload bits.

    UTF-8 Encoding bit layout by codepoint range
    Codepoint RangeBytesBit patternPayload length
    U+0000 - U+007F10xxxxxxx7 bits
    U+0080 - U+07FF2110xxxxx 10xxxxxx11 bits
    U+0800 - U+FFFF31110xxxx 10xxxxxx 10xxxxxx16 bits
    U+10000 - U+10FFFF411110xxx 10xxxxxx 10xxxxxx 10xxxxxx21 bits
  2. Step 2: Obtain the payload bits:

    Convert the hexadecimal code point U+01DE to binary: 00000001 11011110. Those are the payload bits.

  3. Step 3: Fill in the bits to match the bit pattern:

    Obtain the final bytes by arranging the paylod bits to match the bit layout:
